Here is another VIDEO demo'N using GSTREAMER for REMOTE RIG QRQ CW operations on HF

brief demo of a REMOTE RIG OPERATIONS setup to conduct a remote RIG TRANSMIT//RECEIVE session - operating the rig remotely in another room of the house(or from anywhere over the internet) using GSTREAMER SCRIPTS...and a RASPBERRY PI::RIG INTERFACE

SIMPLE DELAY LINEhttps://github.com/swh/lv2/tree/master/pluginsnote: this is crucial to find the best delay timing...so that the PTT has enough time to ACTIVATE FULLY before the CW AUDIO TONE arrives to the RIG for TRANSMIT...this also gives you the MOST HF RECEIVE audio between elements, letters, or words... if you can find the "just enough" delay value...to allow the most HF RX audio to your preference

NOTE: Gstreamer runs very light on the ol RASPBERRY PI 2b used in this demo...and allows the use of ALSA AUDIO ENGINE on the PI's sound card...making things a bit easier to get running...VERSES trying to setup up JACKAUDIO or PULSEAUDIO on the PI

another LIVE video demo of setup for QSO'n CW audio with a friend over the internet using Gtreamer PIPELINES

brief demo of the RECEIVE OP's DESKTOP(LEFT SIDE OF SCREEN)(Spider-Man represents the USB Webcam view of the SENDING OP)

- RIGHT SIDE of the SCREEN is the SENDING OP's DEKSTOP APPsthe sending OP is sending their USB WEBCAM VIEW to the RECEIVING OP''s ip address...as well as sending CW AUDIO(AD5DZ CW Keyboard) and TEXT MESSAGEs(FLdigi)

a 2 channel GSTREAMER opus audio over ip PIPELINE is used to go from CW OP 1 to CW OP 2....the LEFT CHANNEL is for CW AUDIO(mic too if you would like to add voice to the mix) ...the RIGHT CHANNEL is for FLdigi to send the BPSK500 AUDIO for text messaging

NOTE: on the windows OS, you have to jump through a few hoops...at least in this setup....i was using 2 AUDIO REPEATERS to take the audio from BREAKAWAY PIPELINE 1 and BREAKAWAY PIPELINE 2 to route it to the WINDOWS LAPTOP's REALTEK HD SOUND CARD...so the audio can be heard on the win 10 laptop speakers//headphones etc...

the GSTREAMER SCRIPTS used above for windows...are using the "DEFAULT" sound cards for PLAYBACK and RECORD... and to keep the input from going back out the output...and creating a LOOPBACK ...you have to use different soundcards for RECEIVE and TRANSMIT...in this example BREAKAWAY PIPELINES are being utilized for the taskhttps://sites.google.com/site/icwoip/best-virtual-sound-card-for-icw

for the AUDIO REPEATERS, there are a few programs you can use on windows...the idea is to tell FLdigi to use BREAKAWAY PIPELINE 2 to act as the transmitting capture device to go out over GSTREAMER, however, you would not be able to hear FLdigi's sidetone unless you use an audio repeater to take the audio going through BREAKAWAY PIPELINE 2 and send it to the WIN 10 soundcard too, so it can be monitored...etc...same for BREAKAWAY PIPELINE 1...which is acting as the audio device for the RECEIVE GASTREAMER Pipeline from the Linux OP sending to the WIN 10 op
